Abstract
Hydrothermal Synthesis and Electrochemical Studies on Ion- Exchanged Nanostructures of ITO/VO2
Vanadium Dioxide nanostructures were successfully synthesized through hydrothermal procedure and finally they were annealed at 500°C for good uniformity and crystallinity saturation of the nanostructures VO2 (M1). Further the deposition was made on Indium Tin Oxide (ITO) substrates via drop casting and drying from a volatile organic compound solution of VO2 (M1).The coatings were characterized by X-ray diffraction, Raman spectroscopy, SEM and cyclic voltammetry between oxidized and reducing states. It was observed that crystalline vanadium (IV) oxide present the highest intercalation charge with enhanced durability compared to the conductive surface wafer. The importance of achieving single-phase crystalline oxide for the improvement of the coatings performance was highlighted. This study open new avenues for further electrochemical research using this unique material with high conductivity performance.
